使用Lodash将平面数组转换为Id和Name对象数组

Question

let states = ["Georgia","California","FL","TX","MA","NJ"];

如何使用lodash将states数组转换为Id和Name数组集合。

有没有办法以下面的格式转换数组（图片如下所示）：

Answer 1

你真的不需要lodash这样做。

＆＃13;

＆＃13;

let states = ["Georgia","California","FL","TX","MA","NJ"];

let result = states.map((item) => {
return {
      id: item,
      name: item}})
console.log(result)

＆＃13;

＆＃13;

＆＃13;

你和lodash

几乎一样

import _ from 'lodash';

result = _.map(states, (item) => {
return {
      id: item,
      name: item}})

Answer 2

＆＃13;

＆＃13;

let states = ["Georgia","California","FL","TX","MA","NJ"];

const newObj = [];

_.each(states, state => newObj.push({ id: state, name: state }));

console.log(newObj);

＆＃13;

＆＃13;

＆＃13;

＆＃13;

_.each对数组的每个项执行一个函数。有了它，您可以为每个状态创建一个新对象，并将其推送到一个新的数组。注意：这也可以通过内置.map。

的JavaScript来实现
